True Hunger AKA Real Hunger
Fifth stage of fasting marked by a feeling in the throat and/or mouth (as opposed to stomach). Feeding oneself to satisfy true hunger can not lead to weight gain or malnutrition as it is a biological signal to maintain proper body mass and nutrition. The experience of true hunger is said to at least temporarily eradicate all cravings associated with samsara (mental grasping) and to purify and recalibrate the body's desire for biological and social/emotional nourishment. Subsequently, normal everyday hunger can be thought of as "toxic hunger", a state of body/mind that serves to perpetuate cycles of suffering based on the ongoing actualization of impure mental cravings.
